(This is Alex's version of Showoff, so I can share my presentations
\ without waiting for pull requests and updates from busy Scott. It
installs a binary called "showoff" which overwrites the official one,
so if you install this hack, be careful about updates.)
ShowOff is a Sinatra web app that reads simple configuration files for a
presentation. It is sort of like a Keynote web app engine. I am using it
to do all my talks in 2010, because I have a deep hatred in my heart for
Keynote and yet it is by far the best in the field.
\ The idea is that you setup your slide files in section subdirectories and
then startup the showoff server in that directory. It will read in your
showoff.json file for which sections go in which order and then will give
you a URL to present from.
